ELECTRIC SEALIN G-WAX-APPLYIN G DEVICE.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed March 10, 1915. Serial No. 13,366.

To all 107mm t may concern Be it known that I, FAY M. ANDnnws, a citizenof the United States, residing at county of Franklin and State of Ghio,have'invented certain new and useful Improvements in ElectricSealing-lVax-Applying Devices, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to an electric sealing wax applying device, oneobject of the invention being the provision of a hand tool that can berapidly heated by electric current to heat a wax melting and applyinghead against which may be held the wax stick during the melting thereofand the dripping of the melted wax upon the article to be sealed, suchhead being further adapted to be applied to the spread wax upon thearticle to smooth it over and thus economically use the waX.

A further object of the invention is the provision of a means whereby aresistance is placed in circuit with the heating unit, and is instantlycut out and the unit connected directly in the circuit, so that theapplying head under normal conditions is slightly heated so that whenthe full current ,is affecting the heating unit the applying head isbrought to a wax melting temperature in the shortest possible time, andis not maintained at such heat when not in use.

A still further objectof this invention is the provision of a handydevice which can b e quickly attached to a lighting or power y circuit,or where desired to a low voltage battery system, the tool beingprovided with a hand grip which readily presents a push button to cut inand out the resistance, the heating unit carrying member and applyinghead being readily detached also.

With the foregoing and other objects in view and which will appear asthe description proceeds, the invention resides in the combination andarrangement of parts and in the details of Construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made withoutdeparting from the spirit of the invention.

In the accompanying drawings Figure 1 is a perspective view of the complete device.

Fig. 2 is a longitudinal section through the device.

Fig. 3 is an enlarged sectional View through the applying head, itssupport and the heating unit.

Fig. 4c is a plan view of the heating unit.

Referring to the drawings, the numeral 5 designates a hollow or tubularhandle, which is made in any desired shape to conveniently accommodateitself to the hand, the same being provided with the metal shell orsocket 6, at one end. The central connection 7 lis provided with theshell while the resilient contact plate 8 is connected to the shell, theconnection 7 being insulated therefrom so that the two provide thecurrent supplying members of the device. The button 9 is carried by theplate 8 and pro `iects through the opening 10 to be readily accessibleto the thumb of the operators hand while grasping the handle. rl`he wireguiding plug 11 fits in the opposite end of the handle and carries therigid lterminal 12, which engages one terminal of the resistance 13,whose other gages the free end of the terminal plate 15, which isprovided with the contact 16 in the path to be normally engaged by theplate 8, so that under normal conditions the resistance 13 is always incircuit. A branch conductor 17 is connected to the terminal 12 and tothe plate 18, which is in the path to be engaged by the plate 8 when thesame is depressed by the push button 9, thus cutting out the resistance13 and connecting the plate 8 directly to the terminal 12. Anotherconductor 19 is led through the handle 5, and is connected to theconnection 7, and thus forms the other conductor for the current. Theconductors C, are to be connected to a plug or other electricalconnecting medium (not shown) so that the current will be suppliedthrough the usual socket connection to flow at all times while thedevice is ready for use.

The applying head or member 20, is of peculiar construction, beingprovided with the plug 21, which is made in the form of a small lampplug of the usual type, so that when the same is screwed in the shell 6,the proper electrical connection will be made.

porcelain or other insulating disk 22 having its outer face socketed andlined With heat and electrical insulating material 23 is provided, suchmaterial 23 being preferably terminal 1 1 en- 2 Lalanne asbestos ormica, as may be desirable. The heating unit 2i, is laid thereupon andits terminals Q9 and 30 are connected respectively to the connection forengagement with the connection 7 and with the shell of the plug, whilethe applying head is made in the form of a cap or plate 25, whoseportion at the junction of the body and rim is rounded to permit of themelted wax to flow freely thereoi'll and to also permit the outer faceto be wiped or rubbed over the wax to smooth the wax upon the article. Abayonet connection 2G is provided between the disk 22 and the cap sothat the same may be readily attached and detached for insertion of andremoval of the heating unit, and also for the rene val thereof in caseof a burnout.

ln operating the present device, the handle is gripped in one hand, thecurrent to the device having been previously turned on,

and with the 4thumb the button 9 is pressed to eut out the resist-ance13 and thus direct the full current to the heating unit.. which as shownin Fig. ll. consists of a disk 27 of mica with the conductor 28 woundZig-zag thereon, and held in place by the pins a. Mica sheets 3l and 32are disposed upon both sides of the wire Q8 and its supporting disk 27,and thus prevent any short-circuiting when the cap 25 is tight in placeand close upon the unit. By this means the heat is distributed directlyto the cap Q5 so that it is properly heated for melting the wax which isheld in the other hand and rubbed over the outer face of the cap 25,which is slightly inclined to direct the flow of the melted i'axtherefrom and onto the article to receive the wax. YVhen the wax hasthus been applied, to smooth it over the surface, the cap 25 ismanipulated to rest upon the same and be moved back and forth thereoverto thus soften and smooth out the wax, and make a small amount of thewax suffice.

To provide means for suspending the present device the apertured plate33 is carried at one end of the handle while mounted upon the bodythereof adjacent to the apply-head is a two pronged plate 34, whichprevents the device from rolling upon a fiat surface when not in use,and also holds the heated applying head away from the surfaces both whensuspended from the plate 33 and when resting on a flat surface.

l. An electric device for applying sealing Wax, including a tubularhandle having a socket connection in one end thereof, an insulationmember having a concentric plug upon one face and a recess upon theopposite face, a metal covering for the plug, a concentric terminalmounted in the plug, a heating unit comprising a support of insulatingmaterial and a resistance wire upon such material, said unit filling therecess of the insulation member and having the terminals of the wirethereof connected respectively to the concentric terminal and to themetal covering of the plug, and a snap cover fitting over the recessedend of the insulation member and against the heating unit, the outerface and the edge of the cover forming a wax melting and applyingsurface.

rin electric sealing wax applying de vice, including a hollow handle, asocket in one end of the handle, a resilient button actuated contactplate mounted in the handle and connected to one terminal of the socket,a resistance mounted in the handle and having one terminal normally incontact with the contact plate, a conductor bridged around theresistance, a contact connected thereto and in the path to engage theresilient contact plate when the button is depressed, a socketed memberhaving a plug connection for engagement with the socket, a heating unitmounted therein and electrically conneeted with the plug connection, theouter face of the unit being beyond the outer face of the socketedmember, and a wax melting and applying cap fitting over the socketedmember and having its disk portion in contact with the heat-ing unit.
